Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Prepared Fish
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the fish
Boil the fish until quite soft.
Pick the fish into small pieces and lay them on a flat dish.
Season with pepper and coarse sea salt, then add a small piece of butter.
Add the eggs and bake
In a bowl, combine the well-beaten yolks of the eggs with the scalding milk and pour it over the fish.
Beat the egg whites to a stiff froth and spread it over the surface of the dish.
Bake at 350°F (175°C) for half an hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the base of the dish, providing the main body and flaky texture once boiled and picked.
- Egg yolks
- Enrich the custard with fat and help bind the milk into a smooth, set layer.
- Egg whites
- Whipped to a stiff froth, they add lightness and set into an airy topping as it bakes.
- Scalding milk
- Adds moisture and softness, and combines with the yolks to form a custard.
The step that matters
Beat the egg whites to a stiff froth. Egg whites hold air only when beaten to a stiff froth. Under-beaten whites collapse and make the topping dense, while over-beaten whites turn grainy and dry.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
